Vitamin D is your winter friend when there is little sun or when you are under government house arrest!
Vitamin D receptors are found in virtually every type of cell and tissue in the body. Vitamin D is an essential key to accurate DNA and cellular replication. Research shows that vitamin D plays a crucial role in the health of the immune system due to its ability to regulate anti-bactericidal proteins and by stimulating the production of anti-microbial peptides. Vitamin D is a vital component of the immune system’s response against invading microbes that can cause illness, plus it works to limit inflammation within the body.
Since human skin cells are able to manufacture vitamin D using certain wavelengths of UVB light, sunlight will always remain the greatest source of this essential vitamin. However, during the winter or for people living in low sunlight areas, vitamin D must be obtained from food or supplementation.
Vitamin D contributes to:
- the normal absorption/utilisation of calcium and phosphorus
- normal blood calcium levels
- the maintenance of normal bones
- the maintenance of normal muscle function
- the maintenance of normal teeth
- the normal function of the immune system
- Vitamin D has a role in the process of cell division
- Vitamin D is needed for normal growth and development of bone in children
